INFORMATION PROCESSING DEVICE, TERMINAL SEPARATION DETERMINATION SYSTEM AND TERMINAL SEPARATION DETERMINATION METHOD |
| 摘要 |
An information processing device includes: a communication unit that receives positions from a plurality of terminals each capable of calculating a position indicating a latitude and a longitude; an area determination unit that makes a decision, based upon the positions received at the communication unit, as to in which of areas defined in advance based upon latitudes and longitudes thereof, the terminals are located; and a separation determination unit that calculates an extent of separation to which an area where one terminal is located and an area where another terminal is located are separated from each other, and determines whether a predetermined relationship is achieved with regard to the extent of separation between the one terminal and the other terminal. |
